ABSTRACT:
A photographic material suited for forming color radiographs, which material comprises on both sides of a film support at least one silver halide emulsion layer incorporating at least one color coupler that is capable of forming with an oxidized p-phenylenediamine type color developing agent a dye, said color coupler(s) being present in an amount sufficient to allow by exposure and color development with a p-phenylene diamine type developing agent to obtain a spectral density in the material of at least 2.0 with respect to visual filter light, the aggregate amount of silver halide in said material being equivalent to an amount of silver nitrate in the range of 5 g to 1.3 g of silver nitrate per sq.m, the silver halide grain size distribution being such that at least 50% by weight of the silver halide at both sides of the support has a mean grain size smaller than 0.55 .mu.m.
